Active clinical trials for "Prostatic Neoplasms"

Cabazitaxel is a second line chemotherapy drug recently approved for the treatment of metastatic castration-resistant prostate cancer. To investigate whether the precautions for the use of cabazitaxel (contraindications, hepatic function, premedication for hypersensitivity, prophylactic treatments, dose and dose adjustment, as well as conditions of administration) are respected in routine practice, an observational cohort study will be implemented in 32 oncology centres of South-West region of France (CABOBS study). The primary objective of this cohort is to evaluate the conformity of cabazitaxel prescriptions with the Summary of Product haracteristics (SPC) in clinical practice (indications and monitoring methods) and according to the conditions of use. Panel of experts were convened to assess the conformity of prescription of cabazitaxel with a Delphi consensus method. The Delphi method is most suited to areas where a limited number of evidences are available to enable a recommendation or guidelines to be drawn. Moreover, all the evaluated items came from an official document provided by the EMA, the SPC of cabazitaxel. Thus, it is expected from the experts to select the most relevant items. In the frame of the CABOBS study, this method will allow to select items of the SPC list according to their importance, and to define the primary objective of conformity to cabazitaxel conditions of use.

Categorize the clinical parameters and patient determinants that drive physician decision making for treatment selection including Radium-223 for patients with mCRPC.

As choline transport and phosphorylation are upregulated in most cancers, including prostate cancer, positron emission tomography (PET) with choline tracers has found widespread use to detect recurrent disease. However, choline metabolism is not increased in a significant number of cases, probably explaining why this imaging method has been reported to be weakly sensitive and specific fro the detection of prostate cancer lesions, especially at low prostate-specific antigen (PSA) levels. By contrast, prostate-specific membrane antigen (PSMA) is overexpressed in most prostate cancer, suggesting that 68Ga-labelled PSMA ligands could be superior to choline tracers. A meta-analysis published in 2016 (Perera M. and al.), which included 18 studies, of which five reported histolopathologic correlation data for 68Ga-PSMA PET-positive lesions, indicated favourable sensitivity and specificity profiles of 68Ga-labelled PSMA ligands compared to choline-based PET imaging techniques.

This single arm, multi-site pilot study aims to evaluate the feasibility of recruiting and adherence to a 12 week home-based exercise intervention to be conducted in men with metastatic castration resistant prostate cancer (mCRPC) receiving androgen deprivation therapy (ADT). Thirty patients will be enrolled, with the expectation that 20-25 will complete all follow-up measures.

With the general acceptance of MRI and technical advances in biopsy technique of the prostate, new questions arise concerning the selection of patients, the approach, the appropriate technique, the lesions to target and the number of biopsies. The purpose of this study is to address these issues in men suspicious of having prostate cancer and without prior biopsies.

The incidence of prostate cancer is increasing in Hong Kong, as well as that of recurrent or metastatic prostate cancer. Androgen deprivation therapy (ADT) is the standard treatment for recurrent or metastatic prostate cancer, with side effects such as obesity, type 2 diabetes mellitus, metabolic syndrome, osteoporosis and cognitive impairment. With the improvement of treatment, the 5-year survival rate of recurrent and metastatic prostate cancer is up to 20%, and therefore increases the chances of developing such side effects. Due to the introduction of next generation sequencing, investigators have more knowledge of the microbiota in our body, particularly the gut microbiota. Different studies have related gut dysbiosis with obesity, type 2 diabetes mellitus and metabolic syndrome. If investigators can show that ADT is leading to gut dysbiosis, this could be a way in preventing or treating the side effects of ADT. This study aims to identify whether ADT in patients with prostate cancer will have different composition in their gut and urine microbiota.

Prostate cancer is the second leading cause of cancer death in North American men older than 50 years. Prostate specific membrane antigen (PSMA) is a unique membrane bound glycoprotein, which is overexpressed manifold on prostate cancer cells and is well-characterized as an imaging biomarker of prostate cancer. Positron emission tomography / computer tomography (PET/CT) is a nuclear medicine procedure based on the measurement of positron emission from radiolabeled tracer molecules. 68Ga-HBED-CC-PSMA (DKFZ-11) (abbreviated 68Ga-PSMA) is a tracer for prostate cancer PET imaging. The strength of functional imaging methods is in distinguishing tissues according to metabolism rather than structure. Studies have shown that PET/CT imaging with 68Ga-PSMA can detect prostate cancer lesions with excellent contrast and a high detection rate even when the level of prostate specific antigen is low. Study Objectives: The objective of this study is to evaluate if the patient-wide SUVmax on 68Ga-PSMA PET/CT in locoregional and metastatic prostate cancer correlates with histopathologic Gleason score at initial biopsy. It is hypothesized that SUVmax will correlate positively with Gleason score. This is of interest because non-invasive risk stratification may be possible in the future. This will be a single-site JGH-only open label study in which one (1) 68Ga-PSMA PET/CT will be performed on study participants. A PET/CT scan takes 2-3 hours.

In this study we aim to more precisely define the clinical utility of PSMA imaging across a range of clinical indications in men with prostate cancer. To accomplish this, we will make the 18F-DCFPyL PET/CT scan available to urologists, medical oncologists, and radiation oncologists at Johns Hopkins and survey physicians as to the indication for ordering the PET/CT and if a change in management occurred as the result of new information gained from the scan. We believe these data will prove critical for planning future studies aimed at evaluating the efficacy of this test for improving patient outcomes.

Castration-resistant prostate cancer patients with rising prostatic specific antigen (PSA) are eligible for this study. 11C-Choline PET/CT will be used to identify metastatic lesions. Patients with <=3 metastatic lesions will receive stereotactic body radiotherapy (SBRT) as definitive treatment. Blood draws will be taken to monitor the development of anti-prostate cancer immunity

The purpose of this study is to characterize the tolerability profiles of enzalutamide and abiraterone acetate (with prednisone) -with specific focus on central nervous system (CNS) tolerability-and quality of life (QoL) after approximately 2 months of participants starting treatment with one of these agents for metastatic castration-resistant prostate cancer (mCRPC).
